The composition of the dispersion of silver nano-ink:
- Silver nanoparticles (concentration 15-20 wt %)
- Ethylene glycol (as a solvent and a stabilizer)
* Silver nanoink also contains trace amounts of sodium citrate - as stabilizer, sodium nitrate, silver nitrate, boric acid, deionized water.

TEM-image and electron diffraction of silver nanoparticles from dispersion of silver nanoparticles.

According to the results of transmission electron microscopy, the silver nanoparticles have a spherical shape and narrow particle size distribution of 10 ± 2 nm.
